Abstract: L'ARN bicaténaire (dsRNA) induit le silençage de gènes spécifiques d'une séquence lors de la maturation dans plusieurs organismes par un processus connu sous le nom d'interférence ARN (RNAi). Grâce à un système in vitro de drosophiles, nous pouvons démontrer que des fragments d'ARN courts 19-23 nt constituent les médiateurs spécifiques d'une séquence de RNAi. Les ARN interférants courts (siRNA) sont générés par une réaction de maturation de type RNase III à partir de dsRNA longs. Des doubles hélices de siRNA synthétisées chimiquement avec des extrémités 3' en porte à faux médient un clivage ARN cible efficace dans le lysat, et le site du clivage est situé près du centre de la région couverte par le siRNA guide. En outre, nous apportons la preuve que la direction de la maturation du dsRNA détermine si l'ARN cible sens ou anti-sens peut être clivé par le complexe siRNP produit.

Title: Method and apparatus for handoff of a wireless packet data services connection
Inventor: ABROL NISCHAL
IPC: H04W36/14
Filed: 2001-12-04
Granted: 2011-02-15
Abstract: A novel method and apparatus is disclosed for performing seamless handoff of a mobile station (MS) between Radio Access Networks (RANs) that use different types of wireless interfaces. The described embodiments enable an MS to handoff between different RANs without causing routing ambiguity, and without substantial loss of network data. Upon moving from the coverage area of a first RAN using a first wireless interface to the coverage area of a second RAN using a second wireless interface, an MS determines whether routing ambiguity may result from the change of RAN and, based on the determination, triggers a re-registration of its network address. A foreign agent (FA) within a packet data serving node (PDSN) monitors network address re-registrations are being created for the same MS. Based on this determination, the PDSN terminates redundant R-P network connections resulting from movement of the MS between different RANs.

IPC: E21B43/34
Filed: 2002-02-01
Granted: 2010-01-19
Abstract: A method of separating from a mixture of oil-based drilling fluid and sample of formation hydrocarbon, the liquid component of the drilling fluid, which method comprises treating, e.g. chemically, the mixture in a way that selectively substantially affects the liquid component of the drilling fluid , producing one or more treatment products, while leaving the formation hydrocarbon substantially unaffected; and separating the treatment products from the formation hydrocarbon, by solvent extraction. The liquid component of the drilling fluid conveniently comprises one or more esters (which do not occur in significant quantities in naturally occuring formation hydrocarbons ) and which can be hydrolysed to give water-soluble products readily removable from the formation hydrocarbon. The invention is applicable to sampling of formation hydrocarbon using wireline formation testers or sampling tools.

Abstract: The present invention describes new compositions of matter in the form of labeled nucleoside polyphosphates with four or more phosphates. In addition compositions of nucleoside polyphosphates with four or more phosphates that are substrates for nucleic acid polymerases with enhanced substrate properties and methods of using these nucleoside polyphosphates for nucleic acid detection, characterization and quantification are described. The compositions provided by this invention include nucleoside polyphosphate, dideoxynucleoside polyphosphate, or deoxynucleoside polyphosphate analogues which have colorimetric, chemiluminescent, or fluorescent moieties, mass tags or an electrochemical tags attached to the terminal-phosphate. When a nucleic acid polymerase uses this analogue as a substrate, an enzyme-activatable label would be present on the inorganic polyphosphate by-product of phosphoryl transfer. Cleavage of the polyphosphate product of phosphoryl transfer via phosphatase leads to a detectable change in the label attached thereon. When the polymerase assay is performed in the presence of a phosphatase, there is provided a convenient method for real-time monitoring of DNA or RNA synthesis and detection of a target nucleic acid.

Title: Improvements in and relating to medicament injection apparatus
Inventor: LANGLEY CHRISTOPHER NIGEL
IPC: A61M5/145
Filed: 2002-12-16
Granted: 2012-07-10
Abstract: The present invention relates to a medicament injection apparatus, particularly suitable for use by those with diabetes in which, in use, once a desired dosage of medicament has been selected and expelled from the medicament cartridge into the body of the patient, the injected medicament is allowed to disperse locally from the injection site within the patient's body before the needle arrangement is removed from the patient's body. It is considered to be a problem that in known medicament injection devices the injection interval, that is the time elapsed since a previous injection, is measured following completion of a delivery stroke rather than from dispersion of the injected medicament. A medicament injection device is disclosed in which the time elapsed following an injection operation is calculated from the end of a predetermined period during which medicament is permitted to disperse subsequent to completion of an injection stroke.

Abstract: A material handling vehicle includes first and second control handles positioned at opposing ends of an operator compartment. The control system receives inputs from each of the first and second control handles and determines an appropriate travel direction and speed based on those inputs. In a normal mode, one of the handles is in the neutral state, and the input of the second handle is therefore used to direct motion of the truck. In a conflict state, each of the first and second control handles is providing a non-neutral travel request, and the control system determines an appropriate travel direction and speed based on a most conservative choice algorithm.
